Part 4, "His Scandalous Career," begins with another of those cosmic newsreel type openings. The legislation to make pi equal to 3 is deliciously odd.
Now we refocus on Jubal who is thinking about Mike and Jill. Mike has been busy and hasn't dropped by in a while, what with gallivanting into military service (before being discharged) and getting degrees in theology (which it is strongly implied were bought on the fast track).
Ben arrives at Jubal's home and asks for a private discussion.
Before the talk actually gets going, Ben makes a comment on one of Jubal's statues and evokes a mini, Jubal-flavored lesson on the difference between art and abstraction. It's great stuff, a must-read in the original Jubal.
Jubal complains that Duke has run off to be in Mike's church and between Miriam, Dorcas, and Anne, one is getting married and the other two are pregnant.
The two briefly discuss possibilities of fatherhood—Jubal's "to each their own" policy means he hasn't the foggiest—and Ben gives good odds toward Mike.
Small talk dwindles down, and Ben gets to the purpose of his visit. He's visited Mike's church and doesn't seem too excited by what he saw.
Jubal and Ben discuss whether or not Mike's organization is truly a church. Ben says that it's more of a school for the Martian language, but Jubal argues that anything is a church as long the activities are done for the sake of worship.
Well, either way, Ben believes that the setup is a racket.
Ben is about to tell Jubal the story of his visit to Mike's church.
